1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The long-term outcome of laparoscopic surgery for geriatric patients with colorectal cancer remains unclear due to decreased functional reserves and increased medical comorbidities. A meta-analysis was performed in the present study to compare the long-term outcome between laparoscopy and laparotomy. Randomized controlled trials and comparative studies regarding laparoscopy vs. open surgery for colorectal cancer in elderly patients were searched in Pubmed, Embase, and Cochrane library between inception and April 20, 2017. The methodological quality of the cohort studies was evaluated using the Newcastle-Ottawa Scale. The meta-analysis was performed using Stata v12.0 software. Eight cohort studies were enrolled in the meta-analysis. Laparoscopic surgery was associated with a higher 3-year survival rate compared with open surgery [risk ratio (RR), 0.74; 95% confidence interval (CI), 0.61-0.90; P=0.003]. No significant difference was identified between laparoscopy and laparotomy regarding the 5-year survival rate (RR, 0.93; 95% CI, 0.78-1.11, P=0.424). The results of the meta-analysis indicated that the use of laparoscopic surgery on geriatric patients with colorectal cancer should be increased due to more improved long-term outcomes. All the studies included in the meta-analysis were case-control studies with selection bias and other confounding factors. Thus, larger sample sizes and multicenter randomized controlled trials are required to further validate the use of laparoscopic surgery as the preferred therapeutic option for elderly patients with colorectal cancer.
